 remove rubygems from examples
 This patch modifies the examples so that they
 do not use rubygems, and don't modify the LOAD_PATH. The
 library will be installed in a place where ruby can find it,
 and the relative path ../lib is not valid anymore.

 Thanks to Andy Bakun / @thwarted for identifying the issue and
 suggesting the /dev/null workaround.

 added call to mysql_library_init during initialization of the gem
      This call must be performed before trying to call mysql_init from
      multiple threads
      Reference: http://dev.mysql.com/doc/refman/5.1/en/mysql-init.html
      Minimal reproduction of the problem if mysql_library_init is not called
    
        require 'mysql2'
    
        def connect
          Mysql2::Client.new()
        end
    
        threads = [0,1].map {
          Thread.new { connect }
        }
        threads.map(&:join)
        puts "OK!"
